FAN NOISE (HPE 1920-48G - JG927A)

[Kvemi]

Hello.

I know it's probably the case here. But did anyone find a solution how to reduce the noise of the HPE 1920-48G - JG927A switches?

Did not anyone try to disconnect the fan? (If applicable, due to the warranty)

Thank you for every contributor

Hi, AFAIK, only HPE 1920 OfficeConnect Switch Series models non-48 ports and non-PoE/PoE+ are fanless...said so...48 ports model is noisy (I know)...since all models haven't a dedicated Temperature Sensor I think Fan is managed internally - probably (at best) - looking at some related CPU load threshold(s).

I don't know if you can safely disconnect the internal factory installed fan [*]...without incurring, at best, in logged Warnings/Alerts/Errors...at worst, in a non working unit. Never tried, I don't encourage you to do that tweak...48 ports unit and PoE/PoE+ are designed in that way probably because HPE, correctly, thought that they should be installed inside a Rack.

[*] ...or replace with a less noisy fan, see something like doing hacking/tweaking replacing the factory fan with a more silent fan...see here an example on similar 1910 Switch Series <-- clearly...say bye bye to Warranty once you open the unit to do the material tweak.
